This invention relates to improvements in car doors.

One of the objects of the invention is to provide a composite box car door including a braced metal frame of great strength and rigidity, in conjunction with closures or fill stresses andstrains upon thedoor in all "die rections and to prevent warping of the same, thus providing a door which has all the advantages of a heavy, all-steel construction, but resulting ina great reduction in weight 29 and expense, i

'Another object of the invention is to pro. vide a door frame of unitaryconstruction, in which the closures of various forms, such as wood or metal panels or fillers maybe readily applied thereto, the door in its assembled form having substantially the strength and-rigidity of all-metal doors.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings forming part of thisspecification, Figure 1 is a broken, front elevational'view of a car door of the character contemplated by my invention, parts of the same being omitted to more clearly disclose the construction thereof. "Figure 2 is a broken, enlarged horizontal sectional view of the invention substantially on the'line 2-2 of Figure I. Figure 3 is an enlarged vertical, sectional view of the invention substantially on the .line 33 of Figure 1. Figure'4 is an enlarged broken vertical sectional view, similar to Figure 3, of a modified form of my invention. Figure 5 is an enlarged broken,

1 shown in Figure 4, substantially similar to Figure. 2. Figure 6 is an enlargedbroken vertical sectional view, similar to Figure 3 of another modified construction. Figure 7 horizontal sectional view of the invention is a broken, front elevation of still another 1924. Serial No. 722,759.

modified form of my invention. Figure 8 is a sectional view of the invention on the line 8-8 of Figure 7. Figure 9 is a fragmentary sectional view similar to a portion of Figure 8 showing another slightly different applica-' tion of my invention, and Figure 10 is a fragmentary sectional view, similar to Figure I 9, of another modified form of my invention.

Referring to the drawings, A indicates the usual side angle of a door mounting of a box car, B an angle at the opposite side of said door, 0 the top angle, and D a track upon which the door moves, rollers E being shown for this purpose, this being old and well known construction.

In the arrangement illustrated in Figures 1 to' 5, inclusive, a sliding outside door is shown designated generally by reference character F. plated resides in the door per se which is hereinafter more particularly described, such door being of such construction as to be readily applied in connection with the usual standard mountings, the mountings herein shownbeing for the so-called bottom hung door, but it will be readily understood that the door structure is equally Well adapted for use in connection with the so-called i-top hung type of mounting. v

Referring more particularly to the construction of the door F, such door isprovided with top, bottom and side bars 20, 21, 22 and 23, respectively, and in this particular embodiment of the'invention, are preferably in the form, of T=bars, each including a me- The invention herein contemdial flange 24, outer side flanges 25, and inner side flanges 26, the medial flanges 24 being all disposed toward the front of the car door, so that such flanges, in conjunction with the inner side flanges 26 of the T-bars, providea bed for the reception. of panels or fillers of various kinds. v

Braces 27 are preferably provided at the rear face of the door F, which may be diago-' nally disposed asshown, and preferably'in the form of tubes having theirends flattened as shown at 28, and secured to the inner;

flanges 26 of the T-bars 20 and 21, and to the inner flanges 26 of the T-bars 22 and 23',

as clearly shown inf'the Figures 1 to 3,'it be h edial flanges 24 of the T-bars.

ing noted that flattening the ends of the braces 27, and aflixing the same to the inner sides of the inner flanges 26 of the T-bars,

' 5 brings the outer surfaces of such braces sub- 5 stantially level with the inner surfaces of the T-bar frame. A transverse brace 29v 1s connected to the inner flanges 26 of the side bars 22 and 23, for strengthening the frame and serving as a means of connection for some of the panels disposed in the frame;

The door in this form provides a braced bed of boxdike form for the reception of suitable fillers, the sides of such bed being de fined by the medial flanges 24 of the T-bars,

and the bottom of such bed by the braces 27, and the inner side flanges 26 of the T-bars.

Adapted for disposition within the bed so provided is a door or panel 30, in this case beingshown as wood, though other tillers may beused if desired, the door in this instance being provided with the usual reinforcing strips 31 along its edges on the inner surface i of the door, as shown in the drawing, the

strips .31, being preferably recessed to provide openings 32 for tl reception of the braces 27, so that the inner surfaces of the door lie substantially flat upon the inner flanges 26' of the T-bars, and the outer surface of'the door level with the outer edges of The panel 30 is preferably a wood car. door of standard wood construction, being disposed in the bed as described, but of course other panels of various constructions can be uti-- The panel 30 may be secured in position in the bed by. any suitable m ans ,:bolts'32 being' shown, and such bolts preferabl have the heads 33 counter-sunk in the inner flanges 26 6' 5 of the T-bars, and their stems extending through such flanges 26 and. the adjacent edges of the panel 30, there being nuts 34 on the outer ends of the bolts '22 in the usual manner.

4E2 With this arrangement a door is provided which has great strength and rigidity, the door or panel 30 serving to brace the frame, and'in turn being braced by the frame along its edges, and against lateral stress; The conto: struction' thus'provided is economical in manufacture, and has all the advantages of expensive and heavy all-steel construction at a small portion of its cost.

Referring to the form of invention illus- E trated in Figures 4 and 5, inclusive, there is shown a construction generally similar to that just described, having T-bars 40 at its sides, and T-bars 41 42 at the top and bottom respectively, the medial flanges 43 of fi' suchbars being disposed outwardly asbefore, and hming the inner flanges 44 and outer flanges 45 in the same positions. Braces 46,'preferably in the form of tubular members, are provided, and have their ends B? flattened and fastened to the inner flanges 44 i,752,aee

dial flanges 43 of the T-bars shown, and" secured in position by rivets, or other suitable fastening means. The inner edge of such sheet is preferably turned inwardly as shown at 49, and outwardly as at 50, so as to rest against the brace 44. oppositesheet 47, is also inwardly turned as at 52, and then outwardly at 53, such'portion The inner edge of the resting upon the outwardly turned portion i of the other sheet 4' 7, the super-posed layersof material bein secured to the cross'brace44 by means of rivets 54. The outer, and side edges of the last named sheet are turned over the medial flanges 43of theT-bars 40 and 41, and secured by suitable means, preferably rivets 56. 'By this arrangementa hollow metal door is provided having great strength and rigidity, and being very light in weight, and of small cost.

A slightly different construction is in Figure- 6, there beingprovided the T-bars in the same manner as described in Figures 5 and 6. Braces 46 are secured to the-inner flanges of the T-bars as before explained, together with the cross brace 44. Panels 61 in the form'of thin meta'lflsheets have their outer edges 62 turned over the flanges of the T-bars of the fra'me,as shown in Fig? shown ures 5 and 6', and secured thereto by rivets 63: 7

The body portions ofthe-panels 60 and 61 are preferably turned inwardly toward the braces 4621s shown at 64, and such body portions are corrugated or recessed as at 65 for the reception of the braces 46 as shown, so that the inner surfaces of such body portions of the panels are disposed substantially flush with the inner surfaces of the door frame.

central reinforcing channel member 69. It

should be here noted-that with a construction" of this character, the lading in the ear is pre vented from entering the framework- 'of 'th'e door.

The meeting edges of the sheets 60'61 are pref erably turned outwardly andinwardly as in-f dicated at 66, overlap, and are fastened to gether by rivets 67, in this way providing a,

The embodiment'of the invention shown in Figures Tand 8, includes a unitary construe tion formed by 'notching the T-bars 80,81 and 82, at their ends, as indicated in dotted lines, and welding thesame together. The

medial flanges 83 of such T-bars are disposed outwardly as before described, I the Y inner flanges 84 and outer flanges 85 being provided in a like manner. A cross-piece preferably in the formof a T-bar 86, is provided, having its endswelded to the flanges 84 of the side bars 80, and to the medial flanges 83 of such sidebars. Gusset plates 84 are provided at the corners of the frame for strengthening the same against torsional strain. In thisform panel 87 maybe provided with' ventilating openings89. The outer edges 90 of the panels 87 and 88 rest upon the innerflanges 84, and upon the side flanges 91 of the T-bar 86, and the panel 87 may be secured by rivets 92 and the-panel 88 by countersunk bolts 93.

As may be understood, beds provided by the medial flanges 83, inner flanges84 and the medial and side flanges '91 of the cross piece 86', are adapted for the reception of two metal fillers, two wood fillers, or a metal and wood filler, like those just described. In Figure 9 there is shown a construction in which two wood fillers are used, the cross piece 93 and fragments of a frame being illustrated, it being understood that the remainder of the frame is identical to that shown in Figures 7 and 8. In this embodiment it will be seen that the inner edges 94E of the wood fillers rest upon the medial flange 95 of the cross piece 93, and upon the side flanges 96, therev being bolts 97 extending through said side flanges 96 to secure the edges of the wood fillers in position, it being understood that the other edges of the fillers are also secured to the inner flanges of the T-bars of the frame such as the flanges 84 shown in Figures 7 and 8. The remainder of the frame is of the character described heretofore and shown in Figures 7 and 8.

The construction illustrated in Figure 10, contemplates a cross piece 100 in the form of a 2 bar, instead of the T-bar shown hereto fore, and in this constructlon, one edge of a wood filler 101, is shown as disposed within the turned flange 102 of the 2 bar, and resting upon the web 103 of such bar, the oppositely turned flange 10 2 serving as a means upon which the edge of the metal panel105 may be secured by suitable means such as rivets 106. The remainder of the frame is of the same character as previously described and shown.

The above described modifications are but a few of a great variety, the purpose being to indicate the adaptability of a frame made up in the form of a bed for the reception of a single panel, or for a plurality of sectional panels,.the cross bar and frame serving in each instance to provide the beds for panels -of various kinds, and means to which the panels may be secured.

The important features of the invention reside in providing the beds for panels of various kinds, such as wood, sectional wood, metal, or metal and wood, and it is also ointed out that by'utilizing the T-bars in t e construct-ions described and-illustrated, the outer flanges of the T-bars serve as means for mountingthe doors in standard mountings, while the medial flanges of the T-bars and the inner side flanges of such bars operate to provide'the' beds for the panels' Attention is also called to the fact that the construction shown in Figures 7 and'8 is a unit, and may be soldin this form as an article of manufacture, it being necessary only to afterward apply the desired fillers to the door, and fasten them in position by-suitable bolts or rivets,

- apertures for such fastening means being provided in suitable locations.
